Answer 1

Answer:

the answer is ( there is no real solutions) i hoped this help if you need an explanation why let me know :)

Answer 2

Answer:

x = 2√7 or 5.2915

Step-by-step explanation:

x^2 + 28 = 0

first get the variable by itself by subtracting the 28 from both sides. 28-28 cancels and 0-28=-28.

now you have

x^2 = -28

take the square root of x^2 to cancel out the exponent, and then do the same to the other side,

x = √28

x = 2√7 or 5.2915
